My husband talks like a 5 year old and I hate it

When my husband (32) is excited or stressed, he starts talking like a 5 year old. He uses dumb words like "pwetty" and "cwystal cwever" instead of "pretty" and "cool". <br><br>He has nothing wrong with him, he's great otherwise, and this isn't all the time. It's just when he's under a lot of stress or too excited. I've mentioned it to him before because the first time he did it, I thought it was cute. But he continues to do it and I hate it. It makes me want to strangle him when he talks like that. <br><br>It's embarrassing when he does it in public and I just want to die. He won't stop though.
